We are not from Kolkata, but while we were strolling Park Street, We happened to enter Flurry's. Slowly when taken to our seat we saw Au Bon Pain from the window. We were attracted so much to that place that we quit Flurry's and headed there.
It is a self serve cafe but I must say this one was well managed. The staff guided us how to order and manage my choices. At the soup counter I was handed very hygienically the choices of the day. The menu is vast with the choices of salads, sandwiches, bakery items, juices, coffee, soup, other small meals, etc.
We ended up trying so many items; my fantastic discovery was the soup section and the bread bowl. Amazing.
Their breads are freshly baked and bagels are very nice. I loved the way they displayed their history in the cafe, you cannot miss it. There are many stations where you can sit and eat.
